Mapping and monitoring of brainstem surgery.

Handb Clin Neurol 2022 ;186:151-161

Department of Neurosurgery, University Hospital Dubrava, Zagreb, Croatia; Albert Einstein College of Medicine, New York, NY, United States.

The surgical morbidity of brainstem lesions is higher than in other areas of the central nervous system because the compact brainstem is highly concentrated with neural structures that are often distorted or even unrecognizable under microscopic view. Intraoperative neurophysiologic mapping helps identify critical neural structures to avoid damaging them. With the trans-fourth ventricular floor approach, identifying the facial colliculi and vagal and hypoglossal triangles enables incising and approaching the brainstem through the safe entry zones, the suprafacial or infrafacial triangle, with minimal injury.

The building blocks of community health systems: a systems framework for the design, implementation and evaluation of iCCM programs and community-based interventions.

BMJ Glob Health 2022 Jun;7(6)

Malaria Consortium, Niger State, Nigeria.

Introduction: Almost all sub-Saharan African countries have adopted some form of integrated community case management (iCCM) to reduce child mortality, a strategy targeting common childhood diseases in hard-to-reach communities. These programs are complex, maintain diverse implementation typologies and involve many components that can influence the potential success of a program or its ability to effectively perform at scale. While tools and methods exist to support the design and implementation of iCCM and measure its progress, these may not holistically consider some of its key components, which can include program structure, setting context and the interplay between community, human resources, program inputs and health system processes.
